What is CMC in calibration?
Calibration and Measurement Capability is a laboratory's best-case uncertainty, not the accuracy of your instrument.
Ten VIM terms every calibration user should know
Measurand, indication, error, correction, accuracy, precision, trueness, resolution, drift and traceability — defined as the international vocabulary defines them.
Accuracy vs precision in measurement
Precision is about scatter; accuracy is about closeness to the true value. An instrument can be precise and wrong, or accurate on average and noisy.
How to choose a temperature data logger for mapping and monitoring
Match resolution and accuracy to the acceptance criteria, check the calibration offer, and look at memory, battery, export format and response time before price.
